Which process is accompanied by a decrease in entropy for the system?
a. ethanol condenses
b. water evaporates
c. dry ice sublimes
d. sodium chloride dissolves

Answers

Answer 1

The best choice is A. We transition from a gaseous to a liquid state by condensing steam. Entropy declines as unpredictability rises in a liquid transition from a gaseous state.

The degree of disorder in a system is measured by entropy. Disorder refers to the "distance" and "separation" between molecules, particles, etc. Because they have rigid structures as opposed to gases and liquids, which have free structures, solids and crystals have less chaos. Compared to solids and crystalline formations, gases and liquids contain higher levels of chaos. Entropy increases as heat and energy are added, which indicates that disorder is spreading more quickly. Entropy is a measure of how much chaos there is in a system and how rigid and organized it becomes when less heat and energy are contributed.

When equal mass of hot water and oil at the same temperature are allowed to cool water cools slower than the oil why?​

Answers

It is because water has a higher heat capacity as compared to the heat capacity of oil.

The amount of heat that must be applied to an object in order to cause a unit change in temperature is known as the heat capacity or thermal capacity of that object. Heat capacity is measured in joules per kelvin (J/K), the SI unit.

Heat capacity is an example of extensive property. A physical quantity which is an extensive property has a value that is proportional to the size of the system it describes or the amount of matter present in the system. C stands for the heat capacity of an object.

Because water has a higher specific capacity than oil and must expend more energy to cool down, it does so more slowly when two equal masses of hot water and oil are allowed to cool.

Therefore, When the equal mass of hot water and oil at the same temperature is allowed to cool water cools slower than the oil.

The current I in the circuit after first replacing the four sources with a single equivalent source is calculated as 50mA. The circuit can be seen in the attached diagram.

Series combination

If we have to combine the voltage sources, they must be in series. In the question since it is given that same current flows through each, thus it means it is in series.

If we start from the bottom and proceed clockwise in the circuit, we have

we have to  find out constant acceleration (in ) that will bring Haley to this lower speed in the distance available

we know that,

1mile= 1.609km

1 km/h = 5/18m/s

Initial Speed of Haley(u)=  73mph=73×1.609×(5÷18) =32.63m/s

Final Speed of Haley(v)=  55 mph=55×1.609×(5÷18)=24.58m/s

The distance to be travelled  while lowering the speed(S)= 0.5mile=0.805km=805m

according to third equation of motion,v²-u²=2as

as speed is lowering down the acceleration will be in the opposite direction of motion, hence acceleration will be negative, equation will become u²-v²=2as

A motorcycle, starting from rest, has an acceleration of +2.6 m/s². After the motorcycle has traveled a distance of 120 m, it slows down with an acceleration of -1.5 m/s² until its velocity is +12 m/s. a. Calculate the final velocity of the motorcycle after the first 120 m interval.

Answers

The velocity of the motorcycle after the first 120 m is 24.97 m/s and the total displacement of the motorcycle is 280 m.

The acceleration of the motorcycle starting from rest is 2.6 m/s².

The acceleration of the motorcycle after traveling a distance of 120 m id -1.5 m/s² and the velocity is 12 m/s.

The initial velocity of the motorcycle, u = 0 m/s

The acceleration of the motorcycle, a = 2.6 m/s²

Therefore, the final velocity of the motorcycle after d = 120m is:

v² - u² = 2as

v² = u² + 2as

v² = (0)² + 2 × 2.6 × 120

v² =  624

v = √624

v = 24.97 m/s

Now, the motorcycle slows down to -1.5 m/s² and a velocity of 12 m/s.

So, the initial velocity is u = √624 m/s and final velocity is v = - 12 m/s.

So,

v² - u² = 2as

( - 12)² - (√624)² = 2 × -1.5 × d

144 - 624 = - 3 × d

- 480 = - 3d

d = 480 / 3 = 160 m

Therefore, the total displacement of the motorcycle is 120 m + 160 m = 280 m.

which of the following astronomers introduced the most widely accepted hypothesis regarding the origin of the solar system?

Answers

The astronomers introduced the most widely accepted hypothesis regarding the origin of the solar system is Immanuel Kant in 1755.

Newton's equations of gravity and rotatory motion served as the foundation for most of Kant's theories. He believed that primaeval matter, which he believed to have been generated supernaturally, was dispersed throughout the cosmos. Small, chilly, hard particles made up this substance.

Due to the gravitational pull of one another, these particles were drawn to one another.

In his 1755  "The Universal Natural History and Views of the Heavens," Kant discusses astronomy as well as two significant cosmological theories. The first is his "Nebular Hypothesis" on the formation of stars and planets, in which he proposed that faint, thin clouds of dust and gas far out in space would collapse in on themselves under the influence of gravity, forcing them to spin to form a disc. The development of stars and planets from this rotating disc would account for the rotation of Earth and the other planets.

Electrons can move freely between particles when they are in conductors, which are substances. Charge can be transported across the whole surface of an object constructed of a conducting substance.

Charge is swiftly dispersed all across the full surface of the object if it is applied to it at a specific point. The motion of the electrons causes the distribution of charge.

A charged conductor can even transfer its charge to any another object if it comes into contact with that other object. When one object is constructed of a conducting substance, the charge can be transferred from one object to another more easily.

Protons that occupy identical electronic environments are called chemically equivalent, and they will produce only ____________ signal.

Answers

Chemically similar particles are those whose electrical surroundings are the same. If two protons can switch places by rotating or reflecting one another, they are chemically identical.

Protons that are chemically equivalent only generate one signal.

What are protons that are chemically equivalent?

All three Ha protons and all three Hb protons are chemically equal to one another, according to NMR nomenclature. However, the Ha protons and the Hb protons are not chemically similar.

The resonance frequency of the Ha protons differs from that of the Hb protons as a result.

Some examples to illustrate what equivalent and non-equivalent protons are.

A molecule with equivalent protons emits a single signal. The corresponding protons of ethane are four in ethylene, two in acetylene, and six in benzene.

A molecule, each of which results in an absorption and the absorptions are widely separated in the spectrum are called nonequivalent proton.
